.111 rental Application filed .sijiierch H, 19? i lie is known that I,EDWIN Gr. ADAMS, a citizen the United States, residing atlilclv'finnville, in tl1e county of Yemliill, State of Gregon, haveinvented a new and useful Improvement in Tractors, of which thefollowing is a specification, reference be ing; had to the accompanyingdrawings.

My invention relates to a class of devices used generally for drawingplows. but also for other traciion purposes. I

The ebject of my invention to prcvid a tractor wit-l1 n'ieclianisintherein to adjn tne iraction Wheels verlically, ns well the forwardWheels in the same manner, order that they may be caused to run ondiliferenc planes from each other. I nccore; plisli these objects; aswell is others, by the ccnstrnctiem combination and arrangement of partsillustrated in the drawings which form :1 part; hereof.

Like numerals refer to like parts in all figures.

The device has a chassis 7., provided with suitable power generatingmechanism tlicie on and. means to transmit power therefrom to the rectorWheels. A dilierential transmission mechanism is arranged in the earsing 8 situated on the rear part of the chassis. L tractor drive shaft 9extends transversely enrol-1gb the casing 8. ()n the respeciive end .rlthis shaft are the sleeve ll--11. i in the casing the sleeves naveintegral gears 14l-1%l1. The shiift extends through the which aremounted in hearings in the casing. Pinions iO-JO are rigidly secured onthe respective sleeves Without the casing. The sleeve 11 is keyed to theshaft i? lay key 12, While the sleeve llis resemble it'liin the casing aclutch on the d about the shei J in posi- 13 is :irre lricn no 1001gageinent will) the shaft 9. lvl'enns 13 is arranged to operate theclutch 13.

Below the shaft 5) is a differential mechanism having intermediate meansto receive transmission. of power and to transmit the same to the gearsl 2-l4.-. Longitudinal bars 16 are rotatably mounted on concentricbearing liulis 17 Without the casing and inside of the pinions 104.0.The rear end lilie bars 15 are forked. Near the cell 101' cf the barsare formed integral, vertically exl'cnding rnnidrnnis 18 movable throughguides 18rigidly secured on the l ing "Within the intersecns the barsand qrmdt'nnts sliorl'. trans-- whee] she. 19 extend outwardly (Jr inends of (he ell-ales l9 .12 the 1* m5 Of me casing frensverse fulcrumher 22 pivoted center on a pivot 25% extending from 2 inc; The ends thebar 22' s. in tie outward forked en s o"? the. on inn quadrant; bars 16.iii. vertical rod tliremled on its lower part, extends itlirougl :1bearing secured on lllG upper part or ilii casing F3, and Through e.pivoted 2 id il'ireaderf ez'nring ,en The fulcrum bar 22 to one side 0i?its center.

A seat 39 is secured on the rear of the casing for theoperator,

the wheels to any desired position for this purpose. It will also beobserved that when the clutch 13 is not engaged, power is transmitted tothe gears 14-44 as ordinarily through a differential with usualcompensation of movement on the part of the tractors. With the clutchengaged both tractor pinions act in unison and drive the tractors withthe same load and Without slipping.

It will also be seen that the forward wheels may be adjusted to the sameath of travel as the tractors, or to one side thereof, by setting theforward. fulcrum bars on the pivots in different series of theopeningstherein. This arrangement provides a means whereby the forward wheelsautomatically adjust themselves to the plane of travel of the tractorwheels and always in relation to them. In this way one forward wheel canbe driven along and in a plow furrow while the opposite wheel and bothtractor wheels travel on a surface plane at one side of the furrow, asshown in Fig. V. If it is desired to have one tractor and one forwardwheel runin the furrow, an adjustment is made as shown in Fig. III. Inall cases the operator can, as shown, adjust the tractors to any gradeand the forward wheels automatically adjust themselves to that grade,and all the time the chassis is kept in a horizontal position. Thisenables the operator to preserve a steady draft on a plow and to keep itin good alinement on a grade when traveling over the samelongitudinally.

It will be een in Fig. VII that the chassis has been tilted to one side,and the tractor naeaee'r wheels have assumed a similar position at alike angle. The tilting thus shown is accomplished by the operation ofthe hand wheel 27 which has changed the position of thefulcruni bar 22to make this result. It

Having described my invention I claim f A tractor of the characterdescribed having in combination, a chassis with rear tractor wheels andmechanism in and connected withthe rear part of the chassis and saidwheels, whereby the chassis and tractor wheels may be tilted to one sideat a desired angle, and a series of transverse fulcrum bars pivotablelaterally 1n varying positlons on pivots located on the central part ofthe forward end of the chassis, said bars having hanger bars near eachof wheel shafts extending outwardly therefrom, and wheelsrotatablyrmounted on the wheel shafts, said forward mechanism beingarranged and adapted to act automatically in, unison with the operationof the aforesaid rear mechanism to cause the forward wheelscontemporaneously to tilt at a same their ends with desired angle asthat in which the rear wheels are caused to tilt, whether in alinementwith them or in a different path of travel, substantially as described.
